Mark Mellman: Democratic Pollster on how long the spike in support for Kamala Harris will last, Robert F Kennedy Jr.'s endorsement of Trump

Analysts question how long a spike in support for Kamala Harris will last.  

Today marks the final day of the Democratic National Convention, and when Harris is expected to accept her party's Presidential nomination.  

Meanwhile, US media reports independent candidate Robert F Kennedy Jr is planning to end his campaign this week and endorse Donald Trump.  

Democratic pollster Mark Mellman told Mike Hosking the convention will undoubtedly help Harris for now.  

But he says the country is still divided, and it will be a very close race.
